Three miles from town by bike on the north side of Eel Point Rd off Madaket Road. Look for the boulder marked “Dionis.” Some parking. Lifeguard (in season). Sheltered by dunes, calm waters for swimming, safe for children. Hard-pack sand. There is no food concession at Dionis but there are plenty of seashells! Restroom available. Beachgoers can take NRTA shuttle bus to Eel Point Road stop and walk.
